Windows Update Command Line

Now, if you try typing the following command in an Administrator command prompt on Windows 10 or Windows Server 2016, nothing will happen - wuauclt /detectnow

Now, in order to force check Windows Update, follow the below instructions -

  1. Open a Command Prompt with Administrator privileges.
  2. Type in usoclient StartScan
  3. You will see that Windows Update in Settings.exe will start refreshing

Note: USOClient.exe is located in C:\Windows\System32

This will also force the client to report its status to the WSUS server (if configured).

On using Sysinternal's Strings on UsoClient.exe, I found that there are more switches which can be used -

  • StartScan Used To Start Scan
  • StartDownload Used to Start Download of Patches
  • StartInstall Used to Install Downloaded Patches
  • RefreshSettings Refresh Settings if any changes were made
  • StartInteractiveScan May ask for user input and/or open dialogues to show progress or report errors
  • RestartDevice Restart device to finish installation of updates
  • ScanInstallWait Combined Scan Download Install
  • ResumeUpdate Resume Update Installation On Boot
